Coordination of European Research for Advanced Transport Noise Mitigation

Corinair - Corinair is a programme to establish an inventory of emissions of air pollutants in Europe. It was initiated by the European Environment Agency Task Force and was part of the Corine (Coordination of information on the environment) work programme set up by the European Council of Ministers in 1985. In 1995 the Agency's European Topic Centre on Air Emissions (ETC/AEM) was contracted to continue the Corinair programme.

Corine biotopes - The Corine biotopes project was initiated in 1985 to enhance reliable and accessible information about vulnerable ecosystems, habitats and species of important as background information for Community environmental assessment. The project has been aimed to select on basis of biota, the most important sites for nature conservation in each European country, using common methodology, and to gather data about these sites. The Corine biotopes database is an inventory of major natural sites.

Corine land cover - In 1985 the Corine programme was initiated in the European Union. Corine means 'coordination of information on the environment' and it was a prototype project working on many different environmental issues. The Corine databases and several of its programme have been taken over by the EEA. One of these is an inventory of land cover in 44 classes, and presented as a cartographic product, at a scale of 1:100 000. This database is operationally available for most areas of Europe. Original inventories, based on and interpreted from satellite imagery as well as ancillary information sources, are stored within national institutions. The European reference database is owned by GISCO, the European Commission geographical information system, which is a part of the European Statistic Agency, Eurostat. ETC/TE manages the Corine database (the production database) on behalf of EEA and delivers the updated database to GISCO every 12 months.

cadmium

capacity building - Improving and building the technical and managerial skills and resources within an organisation.

car tyre - A rubber ring placed over the rim of a wheel of a road vehicle to provide traction and reduce road shocks, especially a hollow inflated ring consisting of a reinforced outer casing enclosing an inner tube.

carbon capture and storage

carbon dioxide - Gas naturally produced by animals during respiration and through decay of biomass, and used by plants during photosynthesis. Although it only constitutes 0.04 percent of the atmosphere, it is one of the most important greenhouse gases. The combustion of fossil fuels is increasing carbon dioxide concentrations in the atmosphere, which is believed to be contributing to global warming.

carbon dioxide equivalent - A metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential (GWP). Carbon dioxide equivalents are commonly expressed as 'million metric tonnes of carbon dioxide equivalents (MMTCDE)'. The carbon dioxide equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP. MMTCDE = (million metric tonnes of a gas) * (GWP of the gas). For example, the GWP for methane is 21 and for nitrous oxide 310. This means that emissions of 1million metric tonnes of methane and nitrous oxide respectively is equivalent to emissions of 21 and 310 million metric tonnes of carbon dioxide.

carbon dioxide tax - Compulsory tax levied on fuels in accordance with their carbon content, with the aim to encourage using less carbon-intensive fuels and to reduce energy consumption.

End-of-life vehicle directive - Directive 2000/53/EC on end-of life vehicles lays down measures which aim, as a first priority, at the prevention of waste from vehicles and, in addition, at the reuse, recycling and other forms of recovery of end-of life vehicles and their components so as to reduce the disposal of waste, as well as at the improvement in the environmental performance of all of the economic operators involved in the life cycle of vehicles and especially the operators directly involved in the treatment of end-of life vehicles.

Energy consumption - Energy consumption denotes gross inland energy consumption (GIEC) and represents the quantity of energy necessary to satisfy inland consumption of the geographical entity under consideration. Gross inland consumption does not include energy (fuel oil) provided to international maritime bunkers.

Energy dependence rate - The energy dependence rate shows the proportion of energy that an economy must import. It is defined as net energy imports divided by gross inland energy consumption plus fuel supplied to international maritime bunkers, expressed as a percentage. A negative dependency rate indicates a net exporter of energy, while a dependency rate in excess of 100 % indicates that energy products have been stocked.

Energy intensity - Energy intensity denotes the ratio between energy consumption and GDP. It expresses the extent to which there is a decoupling between energy consumption and economic growth. Relative decoupling occurs if energy consumption grows, but at a lower pace than the economy. Absolute decoupling occurs if the economy grows while energy consumption decreases. An absolute decoupling is likely to alleviate the environmental pressures of energy production and consumption.

It also refers to the theory and practice of assessing and controlling factors in the environment that can potentially affect health. Environmental health includes both the direct pathological effects of chemicals, radiation and some biological agents, and the effects (often indirect) on health and well-being of the broad physical, psychological, social and aesthetic environment, which includes housing, urban development, land use and transport.

environmental hygiene - Practical prevention and control measures used to improve the basic environmental conditions affecting human health, for example clean water supply, human and animal waste disposal, protection of food from contamination, and provision of healthy housing, all of which are concerned with the quality of the human environment.

environmental impact - Impacts on human beings, ecosystems and man-made capital resulting from changes in environmental quality.

environmental impact assessment - A technique used for identifying the environmental effects of development projects. As a result of Directive 85/337/EEC (as amended 1997), this is now a legislative procedure to be applied to the assessment of the environmental effects of certain public and private projects which are likely to have significant effects on the environment. An EIA requires a scoping study to be undertaken in order to focus the assessment. This can be carried out in the field or as a desk study depending on the nature/scale of the project.

environmental impact assessment directive - Council Directive 97/11/EC of 3 March 1997 amending Directive 85/337/EEC on the assessment of the effects of certain public and private projects on the environment. According to it, Member States shall adopt all measures necessary to ensure that, before consent is given, projects likely to have significant effects on the environment by virtue, inter alia, of their nature, size or location are made subject to a requirement for development consent and an assessment with regard to their effects.

environmental impact of energy - Energy and environmental problems are closely related, since it is nearly impossible to produce, transport, or consume energy without significant environmental impact. The environmental problems directly related to energy production and consumption include air pollution, climate change, water pollution, thermal pollution, and solid waste disposal. The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution. Burning fossil fuels is also the main contributor to the emission of grenhouse gases. Diverse water pollution problems are associated with energy usage. One problem is oil spills. In all petroleum-handling operations, there is a finite probability of spilling oil either on the earth or in a body of water. Coal mining can also pollute water. Changes in groundwater flow produced by mining operations often bring otherwise unpolluted waters into contact with certain mineral materials which are leached from the soil and produce an acid mine drainage. Solid waste is also a by-product of some forms of energy usage. Coal mining requires the removal of large quantities of earth as well as coal.

It encompasses all the elements that are sometimes addressed separately in mitigation, monitoring and action plans.

environmental management system - A means of ensuring effective implementation of an environmental management plan or procedures and compliance with environmental policy objectives and targets. A key feature on any effective environmental management system (EMS) is the preparation of documented system procedures and instructions to ensure effective communication and continuity of implementation. There are certification systems for EMS ISO 14001 and EC's EMAS scheme (EMAS is now compatible with ISO 14001) which demonstrate that a system is operated to an internationally recognised standard. Alternatively a customised system can be developed addressing the particular needs of the operation.

Also includes dune slack pools. Includes constructed inland freshwater, brackish or saline waterbodies (such as canals, ponds, etc.) which support a semi-natural community of both plants and animals; normally wet habitats which may be dry seasonally (temporary or intermittent rivers and lakes and their littoral zones). Freshwater littoral zones include those parts of banks or shores which are sufficiently frequently inundated to prevent the formation of closed terrestrial vegetation. Excludes permanent snow and ice. Note that habitats which intimately combine waterlogged habitats with pools of open water are considered as complexes.

integrated coastal zone management - Integrated coastal zone management (ICZM) is a dynamic, multidisciplinary and iterative process to promote sustainable management of coastal zones. It covers the full cycle of information collection, planning (in its broadest sense), decision making, management and monitoring of implementation. ICZM uses the informed participation and cooperation of all stakeholders to assess the societal goals in a given coastal area, and to take actions towards meeting these objectives. ICZM seeks, over the long-term, to balance environmental, economic, social, cultural and recreational objectives, all within the limits set by natural dynamics. 'Integrated' in ICZM refers to the integration of objectives and also to the integration of the many instruments needed to meet these objectives. It means integration of all relevant policy areas, sectors, and levels of administration. It means integration of the terrestrial and marine components of the target territory, in both time and space.

integrated product policy - Integrated product policy (IPP) is an approach that begins by asking how the environmental performance of products can be improved most cost-effectively. It is founded on the consideration of the impacts of products throughout their life-cycle, from the natural resources from which they come, through their use and marketing to their eventual disposal as waste. It is also a relatively new approach to environmental policy.

integration of environmental concerns into sectoral policies - Integration can be seen as a concept, a strategy and a process designed to achieve the more sustainable development of economic activities - one of the main conclusions of the Cardiff European Council, June 1998.

intensive farming - Farming characterised by high input use that strives for maximum production, often at the expense of environmental considerations.

intervention scenario - Intervention scenarios (in the context of environmental studies) depict the future consequences of policy interventions. In other words, they describe the future state of society and the environment under influence of directed environmental policies. Intervention scenarios are also known as 'pollution control' or 'mitigation' or 'policy' scenarios.

Kyoto Protocol - The Kyoto Protocol was adopted at the Third Session of the Conference of the Parties (COP) to the UN Framework Convention on Climate Change (UNFCCC) in 1997 in Kyoto, Japan. It contains legally binding commitments, in addition to those included in the UNFCCC. Countries included in Annex B of the Protocol (most OECD countries and EITs) agreed to reduce their anthropogenic emissions of greenhouse gases (CO2, CH4, N2O, HFCs, PFCs, and SF6) by at least 5 % below 1990 levels in the commitment period 2008 to 2012.

Kyoto forest - The Kyoto Protocol and the Marrakech Accords allow industrial countries to discount their greenhouse gas emissions by certain land-use change and forestry activities. These activities are limited to strictly defined cases including afforestation, reforestation and deforestation since 1990, sometimes called 'Kyoto forest'. 'Kyoto Forest' is a minimum area of land of 0.05-1.0 hectares with tree crown cover (or equivalent stocking level) of more than 10-30 per cent with trees with the potential to reach a minimum height of 2-5 metres at maturity in situ. A forest may consist either of closed forest formations where trees of various storeys and undergrowth cover a high portion of the ground open forest. Young natural stands and all plantations which have yet to reach a crown density of 10-30 per cent or tree height of 2-5 metres are included under forest, as are areas normally forming part of the forest area which are temporarily unstocked as a result of human intervention such as harvesting or natural causes but which are expected to revert to forest.

Kyoto mechanisms - Formerly known as flexibility mechanisms. Economic mechanisms based on market principles that parties to the Kyoto Protocol can use in an attempt to lessen the potential economic impacts of GHG (greenhouse gases) emission-reduction requirements. They include joint implementation (Article 6), the clean development mechanisms (Article 12), and emissions trading (Article 17).

land cover - Land cover corresponds to a (bio)physical description of the earth's surface. It is that which overlays or currently covers the ground. This description enables various biophysical categories to be distinguished - basically, areas of vegetation (trees, bushes, fields, lawns), bare soil, hard surfaces (rocks, buildings) and wet areas and bodies of water (watercourses, wetlands).

land development - Planning of infrastructures, services and industrial settlements in order to promote the socio-economic growth of certain land area.

land use - Land use corresponds to the socio-economic description (functional dimension) of areas: areas used for residential, industrial or commercial purposes, for farming or forestry, for recreational or conservation purposes, etc. Links with land cover are possible; it may be possible to infer land use from land cover and conversely. But situations are often complicated and the link is not so evident. Contrary to land cover, land use is difficult to 'observe'. For example, it is often difficult to decide if grasslands are used or not for agricultural purposes. Distinctions between land use and land cover and their definition have impacts on the development of classification systems, data collection and information systems in general.

life cycle assessment - Life-cycle assessment (LCA) is a process of evaluating the effects that a product has on the environment over the entire period of its life thereby increasing resource-use efficiency and decreasing liabilities. It can be used to study the environmental impact of either a product or the function the product is designed to perform. LCA is commonly referred to as a "cradle-to-grave" analysis. LCA's key elements are: (1) identify and quantify the environmental loads involved; e.g. the energy and raw materials consumed, the emissions and wastes generated; (2) evaluate the potential environmental impacts of these loads; and (3) assess the options available for reducing these environmental impacts.

life cycle cost - The cost of a good or service over its entire life cycle.

life cycle impact assessment - A scientific technique for assessing the potential environmental impacts of industrial systems and their associated products. This technique is 'cradle-to-grave' in scope, meaning that it considers impacts at each stage of a product's life-cycle, from the time natural resources are extracted from the ground and processed through each subsequent stage of manufacturing, transportation, product use, and ultimately, disposal.

life-expectancy - The number of years that a person can expect to live on average, based on estimation of data on death rates of the population. Life expectancy depends on age. For example, at birth a person may be expected to live for 75 years, but if the person survives to 75, he or she may be expected to live for another 10 years.

life-year - One year of a non-specified personâs life. Can be used to describe loss of life expectancy. For example, 'thousands of life-years are lost annually in Europe as a result of air pollution'.

lindane - Lindane is an organochlorine pesticide. It is composed of approximately 99 % HCH. Lindane has been used as a broad-spectrum agricultural insecticide since the early 1950s and is 5-20 times more toxic to insects than DDT. It is also used in ointments to treat head and body lice, and scabies. It is poorly soluble in water and rapid bioaccumulation takes place in microorganisms, invertebrates, fish, birds and humans. However, the elimination of lindane from the body is relatively rapid when exposure is discontinued. Workplace exposure has been reported to cause blood disorders, dizziness, headaches, and changes in the levels of sex hormones. The ingestion of large amounts has caused seizures and death. Liver and kidney effects and immune suppression has been observed at moderate ingestion levels. Lindane is considered to be a carcinogen, and has been associated with liver cancer.

lung function - The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

MARPOL Convention - The Convention for the Prevention of Pollution from Ships (MARPOL Convention) is the main international convention covering prevention of pollution of the marine environment by ships from operational or accidental causes.

It was adopted in Barcelona, Spain, in 1975 by 16 Mediterranean States and the EC, under the auspices of the United Nations Environment Programme (UNEP). Its legal framework comprises the Barcelona Convention adopted in 1976 and revised in 1995, and six protocols covering specific aspects of environmental protection. A Mediterranean Commission for Sustainable Development was also established by MAP in 1995 to facilitate the participation of all stakeholders in the Mediterranean area.

Mediterranean pollution monitoring and research programme - The Mediterranean action plan (MAP) and the Barcelona Convention are being implemented through a series of protocols and the programmes are being carried out by relevant MAP regional activity centres. Among these programmes is the long-term programme for pollution monitoring and research in the Mediterranean (Medpol), designed to assess the extent of marine pollution in the Mediterranean.

manure - Animal excreta collected from stables and barnyards with or without litter; used to enrich the soil.

map - A map is a two-dimensional representation of a three-dimensional space. The science of making maps is called cartography.

map projection - A map projection is any of many methods used in cartography (mapmaking) to represent the two-dimensional curved surface of the earth or other body on a plane. Methods for constructing a projection may be mathematical, graphical, or geometric. Regardless of the method, in the end any projection can be expressed mathematically. Flat maps could not exist without map projections. Flat maps can be more useful than models globes in many situations: they are more compact and easier to store; they readily accommodate an enormous range of scales; they are viewed easily on computer diplays; they can facilitate measuring properties of the terrain being mapped; they can show larger portions of the earth's surface at once; and they are cheaper to produce and transport. These useful traits of flat maps motivate the development of map projections.

mariculture - Marine fish farming (aquaculture). Raising of marine animals and plants in the ocean.

marine environment - Marine environments include estuaries, coastal marine and nearshore zones, and open-ocean-deep-sea regions.

marine habitats - One of the main habitat types in the EUNIS habitats classification. Marine habitats are directly connected to the oceans, i.e. part of the continuous body of water which covers the greater part of the earth surface and which surround its land masses. Marine waters may be fully saline, brackish or almost fresh. Marine habitats include those below spring high tide limit (or below mean water level in non-tidal waters) and enclosed coastal saline or brackish waters, without a permanent surface connection to the sea but either with intermittent surface or sub-surface connections (as in lagoons). Rock pools in the supralittoral zone are considered as enclaves of the marine zone. Includes marine littoral habitats which are subject to wet and dry periods on a tidal cycle including tidal saltmarshes; marine littoral habitats which are normally water-covered but intermittently exposed due to the action of wind or atmospheric pressure changes; freshly deposited marine strandlines characterised by marine invertebrates. Waterlogged littoral zones above the mean water level in non-tidal waters or above the spring high tide limit in tidal waters are included with marine habitats. Includes constructed marine saline habitats below water level as defined above (such as in marinas, harbours, etc.) which support a semi-natural community of both plants and animals. The marine water column includes bodies of ice.

market failure - The concept that market does not reflect the full societal costs of all economic activity and, in particular, the economic costs imposed on third parties.

market-based instrument - Market-based instruments seek to address the market failure of 'environmental externalities' either by incorporating the external cost of production or consumption activities through taxes or charges on processes or products, or by creating property rights and facilitating the establishment of a proxy market for the use of environmental services.

marsh - Type of wetland that does not accumulate appreciable peat deposits and is dominated by herbaceous vegetation. Marshes may be either fresh or saltwater, and tidal or non-tidal.

material flow accounting - A monitoring system for national economies based on methodically organised accounts and denoting the total amounts of material used in the economy. Material flow accounting enables monitoring of total consumption of natural resources and the associated indirect flows, as well as calculation of indicators.

material flow analysis - An evaluation method which assesses the efficiency of use of materials using information from material flow accounting. Material flow analysis helps to identify waste of natural resources and other materials in the economy which would otherwise go unnoticed in conventional economic monitoring systems.

material productivity - An indicator of the output or value added generated per unit of material used.

material recovery - Restoration of materials found in the waste stream to a beneficial use which may be for purposes other than the original use.

materials and energy balance - Accounting tables that provide information on the material input into an economy delivered by the natural environment, the transformation and use of that input in economic processes (extraction, conversion, manufacturing, consumption) and its return to the natural environment as residuals (wastes). The accounting concepts involved are founded on the first law of thermodynamics, which states that matter (mass/energy) is neither created nor destroyed by any physical process.

nature reserve - Areas allocated to preserve and protect certain animals and plants, or both. They differ from national park, which are largely a place for public recreation, because they are provided exclusively to protect species for their own sake. Endangered species are increasingly being kept in nature reserves to prevent them from extinction, particularly in India, Indonesia and some African countries. Natural reserves were used once to preserve the animals that landowners hunted, but, in the 19th century, they became places where animals were kept to prevent them from dying out. Special refuges and sanctuaries are also often designated to protect certain species or groups of wild animals or plants, especially if their numbers and distribution have been significantly reduced. They also serve as a place for more plentiful species to rest, breed or winter. Many parts of the world also have marine and aquatic reserves to protect different species of sea or freshwater plant and animal life.

oxygen

ozone - Ozone, the triatomic form of oxygen (O3), is a gaseous atmospheric constituent. In the troposphere - at ground level - it is created both naturally and by photochemical reactions involving gases resulting from human activities (photochemical smog). In high concentrations, tropospheric ozone can be harmful to a wide range of living organisms. In the stratosphere, ozone is created by the interaction between solar ultraviolet (UV) radiation and molecular oxygen (O2). Stratospheric ozone plays a decisive role in protecting life on earth from ultraviolet radiation from the sun.

ozone episode - A period of usually a few days up to 2-3 weeks with high ozone concentrations, characterised by daily exceedances of the thresholds set to protect human health. Ozone episodes occur under specific meteorological conditions characterised by large stagnant areas of high pressure. Since the formation of ozone requires sunlight, ozone episodes mainly occur during summer.

ozone layer - Very diluted atmospheric concentration of ozone found at an altitude of 10 to 50 kilometres above the earth's surface.

ozone layer depletion - The fragile shield of ozone is being damaged by chemicals released on earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons which are used in refrigerators, aerosols, and as cleaners in many industries, and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine. Over the past 30 years ozone levels over parts of Antarctica have dropped by almost 40 % during some months and a 'hole' in ozone concentrations is clearly visible in satellite observations.

ozone precursor - Chemical compounds, such as carbon monoxide (CO), methane (CH4), NMVOCs and nitrogen oxide (NOx), which in the presence of solar radiation react with other chemical compounds to form ozone, mainly in the troposphere.

ozone-depleting substance - A compound that contributes to stratospheric ozone depletion. Ozone-depleting substances (ODS) include CFCs, HCFCs, halons, methyl bromide, carbon tetrachloride, and methyl chloroform. ODS are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere. When they break down, they release chlorine or bromine atoms, which then deplete ozone.

PIC Convention - The Rotterdam Convention on the prior informed consent (PIC) procedure for certain hazardous chemicals and pesticides in international trade was opened for signature in 1998. It will come into force when 50 countries provide final ratification. The Convention will enable the world to monitor and control the trade in various chemicals that threaten human and environmental health. It will give importing countries the power to decide which chemicals they want to receive and to exclude those they cannot manage safely. If trade does take place, requirements for labelling and provision of information on potential health and environmental effects will promote the safe use of these chemicals.

polar vortex - This is a phenomenon that occurs during the polar winter in which stratospheric air moves in a circular motion, with an area of relatively still air in its centre. The temperature in the vortex is approximately -130 degrees F (-80 degrees C), which assists in the formation of polar stratospheric clouds. Though usually more prolonged and colder over Antarctica, the Arctic polar vortex does form to a degree, and when the temperatures there are coldest and the vortex persists, Arctic stratospheric ozone destruction on Arctic polar stratospheric clouds has also been observed.

polychlorinated biphenyl - PCBs are mixtures of 209 different chemicals (cogeners) that come in various forms including oily liquids, solids and hard resins. PCBs are organochlorines that were manufactured until the mid-1980s, after which they were banned due to their toxicity and persistence. PCBs have been widely used as insulators in electrical equipment. They have also been used in the production of hydraulic fluids, lubricants, inks, adhesives and insecticides. They are still found in old electrical equipment and releases into the environment continue from landfills. PCBs are very persistent in the environment, taking years to degrade. They are fat-soluble and bioaccumulate in the tissues of animals. PCBs have become worldwide pollutants due to long-distance transport on air currents. Exposure to PCBs can permanently damage the nervous, reproductive and immune systems of the human body. PCBs are known carcinogens and have been linked with the development of various forms of cancer including skin and liver. In mammals, PCBs are passed via the placenta to developing young in the womb and via breast milk to newborn babies. The disposal of wastes containing PCBs is regulated by the Basel Convention.

polychlorinated triphenyl - Toxic and persistent chemical used as electric insulator.

polycyclic aromatic hydrocarbon - Polycyclic aromatic hydrocarbons (PAHs) are a group of compounds formed during the incomplete combustion of coal, oil, gas, wood, garbage or other organic substances. In most cases PAHs occur as a mixture of several compounds, not as a single chemical. Several PAHs are produced commercially to be used in the industrial organic synthesis. Once released into the aquatic environment, degradation by micro-organisms is often slow, leading to their accumulation in exposed sediments, soils, aquatic and terrestrial plants, fish and invertebrates. In terms of human health, prolonged exposure to PAHs can have a deleterious effect, and individuals exposed to mixtures of PAHs,

polyvinyl chloride - A plastic that is used for many purposes. Various additives, such as plasticisers, lead and cadmium are added to polyvinyl chloride (PVC) to make it usable. Almost every stage of this PVC life-cycle can create pollution problems, for example, environmental contamination with mercury, chlorinated solvents and dioxins. In terms of health, PVC dust can damage the lungs of workers.

precautionary prevention - Action taken to reduce potential hazards.

precautionary principle - (1) Principle adopted by the UN Conference on thr Environment and Development (1992) that in order to protect the environment, a precautionary approach should be widely applied, meaning that where there are threats of serious or irreversible damage to the environment, lack of full scientific certainty should not be used as a reason for postponing cost-effective measures to prevent environmental degradation. (2) The precautionary principle permits a lower level of proof of harm to be used in policy-making whenever the consequences of waiting for higher levels of proof may be very costly and/or irreversible.

prevention of packaging waste - Means the reduction of the quantity and of the harmfulness for the environment of:- materials and substances contained in packaging and packaging waste,- packaging and packaging waste at production process level and at the marketing, distribution, utilization and elimination stages, in particular by developing 'clean` products and technology.

prevention principle - This principle allows action to be taken to protect the environment at an early stage. It is now not only a question of repairing damages after they have occurred, but to prevent those damages occurring at all. This principle is not as far-reaching as the precautionary principle. It means in short terms: it is better to prevent than repair.

price signal - A message sent to customers in the form of a price charged for a commodity; usually indicates a message intended to produce a particular result.

Ramsar list - At the time of joining the Convention on Wetlands (Ramsar Convention), each contracting party undertakes to designate at least one site for inclusion in the list of wetlands of international importance (the 'Ramsar list'). The inclusion of a site in the Ramsar list confers upon it the prestige of international recognition and obliges the government to take all steps necessary to ensure the maintenance of the ecological character of the site. At any time, contracting parties may designate additional wetlands for the list or extend the boundaries of those already included. They select wetlands within their territories on the basis of their international significance in terms of ecology, botany, zoology, limnology or hydrology, as measured by reference to the convention's criteria for identifying wetlands of international importance.

They provide an inventory on the threat to rare plants and animal species. Information includes status, geographical distribution, population size, habitat and breeding rate. The books also contain the conservation measures, if any, that have been taken to protect the species. There are five categories of rarity status: endangered species; vulnerable organisms, which are those unlikely to adapt to major environmental effects; rare organisms, which are those at risk because there are few of them in the world, such as plants which only grow on mountain peaks or on islands; out of danger species, which were formerly in the above categories, but have had the threat removed because of conservation actions; and indeterminate species, which are the plants and animals probably at risk, although not enough is known about them to assess their status.

reforestation - (1) Planting of forests on lands that have previously contained forests but that have been converted to some other use. (2) The reestablishment of forest cover either naturally (by natural seeding, coppice, or root suckers) or artificially (by direct seeding or planting).

SPOT - Satellite Pour l'Observation de la Terre (SPOT).SPOT - the Satellite Earth Observation System was designed in France, and developed with the participation of Sweden and Belgium. The system comprises a series of spacecrafts plus ground facilities for satellite control and programming, image production and distribution.The SPOT satellites capture panchromatic and multispectral imagery in resolutions ranging from 2.5m to 20m. The satellites are fitted with two independent imaging instruments, containing detector arrays that operate using a 'Push Broom' technique. This results in high geometric accuracy across the full 60km wide swath. Each instrument is also fitted with a steerable mirror that allows it to image areas up to 27 degrees east or west off the vertical, which increases the revisit capability and provides stereo imagery for digital elevation modelling. Importantly, the SPOT satellites can be programmed to target client specific areas of interest. History: SPOT 1 was launched on 22 February 1986 with 10m panchromatic and 20m multispectral capability. The satellite was withdrawn from active service on 31 December 1990. SPOT 2 was launched on 22 January 1990 and is still operational. SPOT 3 was launched on 26 September 1993. An incident occurred on 14 November 1997 and after 4 years in orbit the satellite stopped functioning. SPOT 4 was launched on 24 March 1998 and includes an extra Short Wave Infrared band and a (low resolution) vegetation instrument. SPOT 5 was launched on 4 May 2002 with 2.5m, 5m and 10m capability, as well as along-track stereoscopic sensors. System continuity will be assured by a constellation of new-generation minisatellites known as Pleiades.

This directive is aimed at the prevention of major accidents which involve dangerous substances, and the limitation of their consequences for man and the environment, with a view to ensuring high levels of protection throughout the Community in a consistent and effective manner.

Seveso Plants Information Retrieval System - Developed by the Major Accident Hazards Bureau of the Joint Research Centre, the 'Seveso plants information retrieval system' (SPIRS) allows easy visualisation of important hazard and risk related information from such plants and estimation of their hazard and risk potential. The main objective of SPIRS is to support the Member States in their risk management related decision making processes by giving an insight into the geographical component of risk from Seveso plants. This is done by providing a map of all Seveso plants in the EU as well as a flexible tool to rank the hazard/risk potential of such plants.

Seveso plant - The Seveso II Directive aims to ensure high levels of protection against accidents involving dangerous substances. Operators of establishments where certain quantities of dangerous substances are present (called Seveso plants or Seveso installations) are requested to notify the competent authorities and to establish and implement a major implement prevention policy.

social indicator - Social indicators are set of indicators that measure progress towards the policy objectives designed for promoting employment, combating poverty, improving living and working conditions, combating exclusion, developing human resources, etc. Social indicators are also part of Sustainable development indicators as well as the Lisbon strategy. Regarding the Lisbon strategy the role of social indicators is ' to describe the present situation and main challenges for poverty and social exclusion policies in the EU, provide a launched for strengthening policies and programmes across the EU - covering the key aspects of monetary poverty, such as level, persistence, depth, changes through time, as well as the key breakdowns by gender, age, household types and occupation, the multidimensional aspect of poverty in the areas of employment, housing, health and education - areas to which Member States have devoted a particular attention in their National Action Plans against poverty and social exclusion'.

software for fishery statistics

soil - Soil is a three-dimensional body performing a wide range of socio-economic and ecological functions. It is a complex media formed by a porous matrix, in which air, water and biota occur together with the fluxes of substances and fluids between these elements. Alteration of soil processes leads to changes in the functioning of ecosystems, and many environmental problems which become apparent in other media actually originate within the soil.

soil acidification - A naturally occurring process in humid climates that has long been the subject of research, whose findings suggest acid precipitation on the productivity of terrestrial plants is summarised as follows: as soil becomes more acidic the basic cations (Ca, Mg) on the soil exchange are replaced by hydrogen ions or solubilized metals. The basic cation, now in solution, can be leached through the soil. As time progresses the soil becomes less fertile and more acidic. Resultant decreases in soil pH cause reduced, less-active population of soil microorganisms, which in turn slow decomposition of plant residues and cycling of essential plant nutrients.

soil compaction - An increase in bulk density (mass per unit volume) and a decrease in soil porosity resulting from applied loads, vibration or pressure. More compacted soils (or other materials) can support greater loads (load-bearing capacity). Bulk density can be increased by controlling the moisture content, compaction forces and treatment procedures, as well as by manipulating the type of material being compacted.

soil conservation - Management of soil to prevent or reduce soil erosion and depletion by wind and water. Preservation of soil against deterioration and loss by using it within its capabilities; application of conservation practices needed for its protection and improvement.

soil erosion - Soil erosion consists in the removal of soil material by water or wind. It is a natural phenomenon but it can be accelerated by human activities.

soil fertility - The status of a soil with respect to the amount and availability to plants of elements necessary for plant growth.

soil formation - The combination of natural processes by which soils are formed. It is also known as pedogenesis. The most important soil-forming factors are parent material, terrain, climate, aspect, vegetation cover, microorganisms in the soil and the age of the land surface. Some pedologists would add to this list the influence of human activities. All the factors exhibit varying degrees of interrelationship and some are more important than others, with climate often being singled out as the most important.

soil leaching - The removal of water or any soluble constituents from the soil. Leaching often occurs with soil constituents such as nitrate fertilisers with the result that nitrates end up in potable waters.

soil organic carbon - Carbon residue retained by the soil in humus form. It improves soil structure and fertility.

soil pollution - Modifications of soil features or, more generally, of its chemical and biological balance, caused by the discharge of polluting substances.

soil porosity - The volume of water that can be held in a soil. Also refers to the ratio of the volume of voids to the total volume of the soil.

soil salinisation - The accumulation of soluble mineral salts near the surface of soil, usually caused by the capillary flow of water from saline ground water. Where the rate of surface evaporation is high, irrigation can exacerbate the problem by moistening the soil and causing water to be drawn from deeper levels as water evaporates from the surface. The evaporation of pure water leaves the salts behind, allowing them to accumulate, and they can reach concentrations that are toxic to plants, thus sterilising the land.

soil sealing - Soil sealing refers to changing the nature of the soil such that it behaves as an impermeable medium (for example, compaction by agricultural machinery). Soil sealing is also used to describe the covering or sealing of the soil surface by impervious materials by, for example, concrete, metal, glass, tarmac and plastic.

soil texture - 1) Refers to the relative proportions of the various size groups (sand, silt and clay) of the individual soil grains in a mass of soil. 2) Classification of soil by the proportion and graduations of the three size groups of soil grains, i.e., sand, silt and clay, present in the soil.

solar collector - Device which converts the energy from light into electricity. The collector system contains a concentrator and a receiver. The concentrator redirects and focuses sunlight on the receiver by using mirrors or lenses, and the receiver absorbs solar radiation and converts it to heat.

solar energy - The energy transmitted from the sun in the form of electromagnetic radiation. The most successful examples of energy extraction from the sun are so far solar cells used in satellites and solar collectors used to heat water.

solid waste - Discarded solid materials. Includes agricultural waste, mining waste, industrial waste and municipal waste.

sorption - The action of soaking up or attracting substances; process used in many pollution control systems.

source principle - The environmental damage should preferably be prevented at the source, rather than by using the 'end-of-pipe technology'. This principle also implies a preference for emission standards rather than environmental quality standards, especially to deal with water and air pollution.

special area of conservation - Site designated according to the habitats directive. Special area of conservation means a site of Community importance designated by the Member States through a statutory, administrative and/or contractual act where the necessary conservation measures are applied for the maintenance or restoration, at a favourable conservation status, of the natural habitats and/or the populations of the species for which the site is designated.

story-and-simulation approach - An approach to (environmental) scenario analysis that combines qualitative and quantitative information based on two main elements: a narrative (story) and results from model calculations (simulation). The narrative describes in story-form how relevant events, key driving forces and step-wise changes unfold in the future. The results from model calculations complement the storyline by presenting numerical estimates of environmental indicators.

storyline - A storyline is a narrative description of a scenario which highlights its main features, and the relationships between the scenario's driving forces and its main features.

strategic environmental assessment - A similar technique to environmental impact assessment (EIA) but normally applied to policies, plans, programmes and groups of projects. Strategic environmental assessment (SEA) provides the potential opportunity to avoid the preparation and implementation of inappropriate plants, programmes and projects and assists in the identification and evaluation of project alternatives and identification of cumulative effects. SEA comprises two main types: sectoral SEA (applied when many new projects fall within one sector) and regional SEA (applied when broad economic development is planned within one region).

strategic environmental assessment directive - Directive 2001/42/EC on the assessment of the effects of certain plans and programmes on the environment. Its objective is to provide for a high level of protection of the environment and to contribute to the integration of environmental considerations into the preparation and adoption of plans and programmes with a view to promoting sustainable development, by ensuring that an environmental assessment is carried out of certain plans and programmes which are likely to have significant effects on the environment.

The 5th environmental action programme refers to sustainable development as 'development, which meets the needs of the present without compromising the ability of future generations to meet their own needs'. Sustainable agriculture entails the management of natural resources in a way, which ensures that the benefits are also available in the future. A broader understanding of sustainability extends to the protection of landscapes, habitats, and biodiversity, and to overall objectives such as the quality of drinking water and air.

sustainable consumption and production

sustainable developent indicators - Sustainable development indicators are indicators that measure progress made in sustainable growth and development. They can provide an early warning, sounding the alarm in time to prevent economic, social and environmental damage. They are also important tools to communicate ideas of sustainable development. Indicators for monitoring progress towards sustainable development are needed in order to assist decision-makers and policy-makers at all levels and to increase focus on sustainable development. Beyond the commonly used economic indicators of well-being, however, social, environmental and institutional indicators have to be taken into account as well to arrive at a broader, more complete picture of societal development. A core set of 58 indicators and methodology sheets are now available for all countries to use. This core set was adopted by the Commission on Sustainable Development (CSD) at its Third Session in April 1995.

A fully formed virus consists of nucleic acid(DNA or RNA) surrounded by a protein and lipid (fat)coat. The nucleic acid of the virus interferes with nucleicacid-synthesizing mechanism of the host cell, organizing it to produce more viral nucleic acid. Viruses cause many diseases (e.g., mosaic diseases of many cultivated plants, myxomatosis, foot and mouth disease, the common cold,influenza, measles, poliomyelitis). Many plant viruses are transmitted by insects, some by eelworms. Animal viruses are spread by contact, droplet infection or by insect vectors and some are spread by the exchange of body fluids.

waste-to-energy scheme - Waste-to-energy scheme means incineration of waste with recovery of generated energy. Waste-to-energy schemes turn waste into steam or electricity to heat, cool, light and/or otherwise power homes and industry through the process of combustion. Just as coal, oil or natural gas is burned in boilers to generate electricity, waste is used as a fuel to generate power.

wastewater treatment plant - (1) Plant where, through physical-chemical and biological processes, organic matter, bacteria, viruses and solids are removed from residential, commercial and industrial wastewaters before they are discharged in rivers, lakes and seas. (2) Installations to render wastewater, sludge, storm water or cooling water fit to meet applicable environmental standards or other quality norms for recycling or reuse.

water abstraction - Water removed from any sources, either permanently or temporarily. Mine water and drainage are included. Similar to water withdrawal.

water abstraction charge - Imposed fee, expense or cost for the abstraction of water. Water abstraction charges can take the form of nominal licence fee linked to an abstraction permit regime or they can vary depending on the quantity used.

water body - 1) Also 'waters'. Landscape features comprising any body of water, standing of flowing, including the water column, littoral zones and bed, such us the sea, lakes, river or stream, etc. 2) Any mass of water having definite hydrological, physical, chemical and biological characteristics and which can be employed for one or several purposes.

water column - The open-water environment, as distinct from the bed or shore, which may be inhabited by swimming marine or freshwater organisms.

water consumption - Water abstracted which is no longer available for use because it has evaporated, transpired, been incorporated into products and crops, consumed by man or livestock, ejected directly into sea, or otherwise removed from freshwater resources. Water losses during transport of water between the points or points of abstractions and point or points of use are excluded.

water cycle - The paths water takes through its various states - vapour, liquid, solid - as it moves throughout the ocean, atmosphere, groundwater, streams, etc.

water demand - Water demand is defined as the volume of water requested by users to satisfy their needs. In a simplified way it is often considered equal to water abstraction, although conceptually the two terms do not have the same meaning.

water demand management - Water demand management refers to the implementation of policies or measures which serve to control or influence the amount of water used.

water distribution system - The system of pipes supplying water to communities and industries.

water erosion - The breakdown of solid rock into smaller particles and its removal by water. As weathering, erosion is a natural geological process, but more rapid soil erosion results from poor land-use practices, leading to the loss of fertile topsoil and to the silting of dams, lakes, rivers and harbours. There are three classes of erosion by water: (a) splash erosion occurs when raindrops strike bare soil, causing it to splash, as mud, to flow into spaces in the soil and to turn the upper layer of soil into a structureless, compacted mass that dries with a hard, largely impermeable crust; (b) surface flow occurs when soil is removed with surface run-off during heavy rain; (c) channelised flow occurs when a flowing mixture of water and soil cuts a channel, which is then deepened by further scouring. A minor erosion channel is called a rill, a larger channel a gully.

water exploitation index - Annual total abstraction of fresh water divided by the long-term average freshwater resources.

water framework directive - Directive 2000/60/EC establishing a framework for the Community action in the field of water policy. It aims to secure the ecological, quantitative and qualitative functions of water. It requires that all impacts on water will have to be analysed and actions will have to be taken within river basin management plans.

water pollution - Presence in water of harmful and objectionable material - obtained from sewers, industrial wastes and rainwater run-off - in sufficient concentrations to make it unfit for use.

water pricing - Applying a monetary rate or value at which water can be bought or sold.

water quality - Physical, chemical, biological and organoleptic (taste-related) properties of water.

water resources - Distinction is made between renewable and non-renewable water resources. Non-renewable water resources are not replenished at all or for a very long time by nature. This includes the so-called fossil waters. Renewable water resources are rechargeable due to the hydrological cycle unless they are overexploited, comprising groundwater aquifers and surface water like rivers and lakes. Internal renewable water resources comprise the average annual flow of rivers and groundwater generated from endogenous precipitation.

water reuse - Treated wastewater can be indirectly reused when it is discharged into a watercourse, diluted and used again downstream. Direct reuse means the direct supply of treated effluent from the treatment plant to the user. It also can apply to the recharge of an aquifer.

water stress - Water stress occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use. Water stress causes deterioration of fresh water resources in terms of quantity (aquifer over-exploitation, dry rivers, etc.) and quality (eutrophication, organic matter pollution, saline intrusion, etc.).

water supply - Water supply refers to the share of water abstraction which is supplied to users (excluding losses in storage, conveyance and distribution).

water table - The top of the water surface in the saturated part of an aquifer.

water use - Three types of water use are distinguished: (a) withdrawal, where water is taken from a river, or surface or underground reservoir, and after use returned to a natural water body, e.g. water used for cooling in industrial processes. Such return flows are particularly important for downstream users in the case of water taken from rivers; (b) consumptive, which starts with withdrawal but in this case without any return, e.g. irrigation, steam escaping into the atmosphere, water contained in final products, i.e. it is no longer available directly for subsequent uses; (c) non-withdrawal, i.e. the in situ use of a water body for navigation (including the floating of logs by the lumber industry), fishing, recreation, effluent disposal and hydroelectric power generation.

waterborne disease - Disease that arises from infected water and is transmitted when the water is used for drinking or cooking (for example, cholera or typhoid).

waterlogged - Saturated, with the water table at or above ground level for at least half of the year.

watershed - The land area that drains into a stream; the watershed for a major river may encompass a number of smaller watersheds that ultimately combine at a common point.

watt hour

weed - Simply any plant growing where it is not wanted. In agriculture, used for a plant which has good colonising capability in a disturbed environment, and can usually compete with a cultivated species therein. Weeds are typically considered as unwanted, economically useless or pest species.

wetland - Areas that are inundated by surface or ground water with frequency sufficient to support a prevalence of vegetative or aquatic life that requires saturated or seasonally saturated soil conditions for growth or reproduction.

what if scenario - The term 'what if' is used to reflect potential effect under different assumptions.

wild relative - Plant or animal species that are taxonomically related to crop or livestock species and serve as potential sources for genes in breeding of new varieties of those crops or livestock.

wild species - Organisms captive or living in the wild that have not been subject to breeding to alter them from their native state.

wildlife - Animals and plants that grow independently of people, usually in natural conditions.

willingness to accept - The amount of compensation an individual is willing to take in exchange for giving up some good or service. This may be elicited from stated or revealed preference approaches.

willingness to pay - The amount an individual is willing to pay to acquire some good or service. This may be elicited from stated or revealed preference approaches.

wind - The motion of air relative to the earth's surface; usually means horizontal air motion, as distinguished from vertical motion.

wind energy - Energy extracted from wind, traditionally in a windmill, but increasingly by more complicated designs including turbines, usually to produce electricity but also for water pumping. The power available from wind is proportional to the area swept by the rotating place and the cube of the wind velocity, but less than half the available power can be recovered.

wind erosion - The breakdown of solid rock into smaller particles and its removal by wind. It may occur on any soil whose surface is dry, unprotected by vegetation (to bind it at root level and shelter the surface) and consists of light particles. The mechanisms include straightforward picking up of dust and soil particles by the airflow and the dislodging or abrasion of surface material by the impact of particles already airborne.

working group

world heritage site - The Convention concerning the Protection of the World Cultural and Natural Heritage (the World Heritage Convention) was adopted by the General Conference of UNESCO in 1972. It covers both cultural and natural heritage sites. 'Cultural heritage' is a monument, group of buildings or site of historical, aesthetic, archaeological, scientific, ethnological or anthropological value. 'Natural heritage' designates outstanding physical, biological, and geological features; habitats of threatened plants or animal species and areas of value on scientific or aesthetic grounds or from the point of view of conservation. More than 170 countries have adhered to the Convention.

year

zoning - The control of land use by only allowing land development in fixed areas or zones.

zoo - All permanent establishments where animals of wild species are kept for exhibition to the public for 7 or more days a year, with the exception of circuses, pet shops and establishments which Member States exempt from the requirements of this Directive on the grounds that they do not exhibit a significant number of animals or species to the public and that the exemption will not jeopardise the objectives of this Directive.

zoobenthos - Invertebrate animals that live in or on seabed habitats, including the intertidal zone.

zoology - The study of animals, including their classification, structure, physiology, and history.

zooplankton - Microscopic animals that float freely in the open water.
